I do not know how to make sure that firefox opens links in a new tab. In Preferences I checked the option 'always open in a new tab instead of a new window' but that does not work: links are always opened in the same tab but not in a new one. How to make that happen?

New Tabs and even sometimes first tab do not load any page and become just "dead"

Open in New Tab and Ctr T is like a roll of dice now, the same page sometimes loads sometimes doesn't, usually closing FF and re-opening solves it.

This has been happening quite frequently so I tried several builds and solutions, uninstalled and reinstalled with new profile, safe mode, no add-ons or themes, both 32 and 64 bit, ESR, etc.. (I'm on Win10 64 bit)

If anyone is experiencing something similar or have an idea let me know please
I've been using Firefox for longer than I remember and I would hate to switch now

Sometimes when I go to a website a completely new window opens in the background. I would prefer to keep all the windows open under tabbed browsing. I did a bit of searching, including searching for a help contact but I could not find an answer.

Using Mac OS X High Sierra with Firefox version 70.0 (64 bit). Firefox is loading homepage twice, in the same tab, at startup only. It works normally when going to homepage from another website and when opening another tab. Tried setting different homepages and they all load twice but only at startup. Any solution?

The add-on extension "NewTabURL" (by "sogame") provided the option I want and used for a number of years. But it stopped working when Firefox was updated to version 16.0. When I click for a new tab, all I get is a completely blank tab. How can I automatically have the new tab always be a copy of the current active tab?

Can the extension "NewTabURL" be revised to work in version 16 and/or version 17? If not, how else can I get the new tab functionality that I desire? I can't seem to find any other extension that provides that functionality.

I also looked at the changelog for Firefox 17 but can't see any explanation for this change in behaviour, although I wonder whether this might have something to do with it "772319 No option to disable the "Close other tabs" prompt."

As I use Tab Mix Plus (add-on), I've also checked Firefox in safemode and have found the native tab warnings not working, so have concluded it's an issue with Firefox (rather than something to do with an extension).

I've checked "about:config" and "browser.tabs.warnOnClose" is set to true, as is "browser.tabs.warnOnCloseOtherTabs".

The new tab (+) is not working. The File/New Tab function does not work either. Both had been working properly until midday today. I have not added any software, plug-ins, or extensions today, I do not have the Ask toolbar. I have tried several of the suggestions made on this site to no avail.

I have been forced to create a new profile because, after an update to version 17.0, Firefox persisted in opening tabs from the previous session. Unfortunately another problem developed, namely, the constant appearance of a series of thumbnails in a new tab, a facility that I definitely do not want. After consulting Mozilla help and forums I tried all of the suggested solutions to no avail.

I eventually went about:config browser.newtabpage.enabled and rendered it false. The annoying thumbnails have disappeared!!!!!

Recently, FF has started opening my last tabs when I start a fresh session. I have already checked to make sure that none of the applicable settings are enabled, such as under Options->General: When FF starts "SHOW MY HOMEPAGE" is selected. But for some reason, it opens my last session. The only way I've been able to get it to stop doing this is by having it delete my browsing history after I close the session. I don't want this since I often use my history to re-find information I need for class research. I have made certain that all my settings are the same from before FF started doing this. It only started doing this after the computer was turned off for a long weekend.

I've already searched through the Mozilla help pages and all I can find is how to restore the previous session or similar. I don't want to restore my previous session, I want it to stop restoring my previous session without having to delete my browsing history each time.

It seems intuitive to me that opening multiple tabs (w/ one copy of Firefox running) should be more efficient than opening multiple copies of Firefox, but I can't find anything about this when I google it or search your site. Which is better, or does it not matter? If one is better over the other, is there a lot of difference?

f it matters, I usually have 4-6 tabs open, but sometimes 10 or so. He usually has 4-6 copies of Firefox running, w/ 1 or 2 tabs each.

I have history turned off so images aren't cached for the New Tab Page and have to be reloaded when Firefox is restarted. Also, some of the sites that I have pinned are using HTTPS and wont allow their images to be cached.

Is there a way for me to set a custom image for each pinned website? Either a custom screenshot that isn't in the cache or an icon of some sort? Anything would be better than a blank box there.

This just began to happen yesterday. I have a MacBook Pro 10.7.5.
I can always get to the first page that I open in a new browser, but any page after that that I try to open in a new tab will seem to load but the page is blank.
This does not just happen with one website I have tried myriad of different sites.. only the first tab loads in a new browser. I am having to open a new browser if i want to go to another link - very frustrating..

In FF 17.0.1 I have several bugs to mention. I am only able to open bookmarks by right clicking them and selecting Open In New Tab from the drop down menu. I am unable to open a new tab by clicking on the new tab button or by clicking open new tab from the FF drop down menu at top of browser. Also, none button work in FF, such as Home, Back, Forward, or refresh. This is so aggravating!!
